Abstract
The utility model discloses a kind of centering top plates for benchmark missing column, including top plate (1), top plate (1) is discoid, the bottom center of top plate (1) is machined with centre bore (2), the disk side of top plate (1) is equipped with four threaded holes (3) being uniformly distributed along the circumference, and is equipped with adjusting screw (4) in each threaded hole (3).The utility model can reduce the clamping times of the number and column of repairing centre bore, improve production efficiency, guarantee the requirement of column concentricity, reduce waste of material, reduce production cost.
Description
Technical field
The utility model relates to a kind of centering top plates for benchmark missing column, belong to the processing of benchmark missing part
Technical field.
Background technique
During processing column, sometimes because processing fault caused by non-stop layer hole or centre bore it is not positive at
Product part；Or in handling process accidentally by finished parts centre bore damaged condition.Since finished parts have been machined to the margin of tolerance substantially
Within, the surplus very little that can generally reprocess, or the surplus that do not reprocess.It therefore, is in the prior art usually by these
Benchmark lack column by scrap processing.Waste of material is caused, production cost is increased.
Utility model content
The purpose of the utility model is to provide a kind of centering top plates for benchmark missing column, to some tools
There is the finished product column of scrapping of certain machining allowance to be repaired, make qualified product, to reduce waste of material, reduce life
Produce cost and overcome the deficiencies in the prior art.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of centering top plate for benchmark missing column of the utility model, including top plate, top plate are discoid, top
The bottom center of disk is machined with centre bore, and the disk side of top plate is equipped with four threaded holes being uniformly distributed along the circumference, in each threaded hole
Equipped with adjusting screw.
In aforementioned centering top plate, the center line of four threaded holes with the central axis of top plate.
By adopting the above-described technical solution, the utility model is compared with prior art, the utility model can be to some
Finished product column of scrapping with certain machining allowance is repaired, and waste of material is reduced, and reduces production cost.The utility model
Without repairing the centre bore or datum level of column, and it can be reduced the clamping times of part, to improve production efficiency and overcome
The deficiencies in the prior art.The utility model have versatility, suitable for process part non-stop layer hole, centre bore not just,
Bending deformation is big to wait the case where really losing benchmark, there are also finished product axial workpiece ellipse, is bent, the reparation situation of out-of-alignment.For
Finished product axial workpiece has oval, bending, out-of-alignment problem.Table adjustment table everywhere can be played by many places by the present apparatus
Difference repairs the geometric tolerance of part with the lower variation of tolerance value of part, is qualified products after correcting the part.This is practical new
Type can reduce the clamping times of column in centering process, improve production efficiency, preferably guarantee the coaxial of column
Degree etc. requires.
Detailed description of the invention
Fig. 1 is the schematic diagram using lathe process column；
Fig. 2 is the schematic diagram using grinding machine processing column；
Fig. 3 is the structural schematic diagram of the utility model centering top plate.
In the figure, it is marked as 1- top plate, 2- centre bore, 3- threaded hole, 4- adjusting screw, 5- column, 6- chuck, 7-
Centering top plate.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
The utility model is according to constructed by a kind of aligning method of following benchmark missing columns and for this method
, this method is to use the fixture with two freedom degrees of X, Y to carry out clamping at benchmark missing column both ends, by adjusting circle
The X at column both ends, Building Y cursor position, the rotary shaft of the central axis and equipment that make column essentially coincide；Specific adjustment process is:
Amesdial is fixed through dial framework, and the stylus of amesdial is withstood in the outer circle of column, and then one side rotational circle column, observes thousand on one side
The beating scope for dividing meter reading determines column both ends X, Y according to the reading beating scope in the middle part of column with both ends amesdial
The adjustment data of coordinate, until being 0 or reaching within allowed band with the reading beating scope of both ends amesdial in the middle part of column
When, then carry out turning or grinding.Fixture with two freedom degrees of X, Y is different because of processing method difference, using turning
When processing, as shown in Figure 1, column one end uses the chuck with two freedom degrees of X, Y to carry out clamping, column is another
End carries out clamping using the centering top plate with two freedom degrees of X, Y, and top on tail stock directly withstands on centering top plate
On centre bore；Turnery processing is directly carried out after centering.When using grinding, as shown in Fig. 2, column both ends, which are all made of, to be had
X, the centering top plate of two freedom degrees of Y carries out clamping, the top center for directly withstanding on column both ends centering top plate on grinding machine
Kong Shang；Grinding is directly carried out after centering.When amesdial is arranged it is ensured that the X of column has amesdial to Y-direction, together
The X of time control rounding column is to the runout error with Y-direction.
The a kind of of the utility model of the above method is constructed and be used for according to the above method lacks column for benchmark
Centering top plate, as shown in figure 3, include top plate 1, top plate 1 be it is discoid, the bottom center of top plate 1 is machined with centre bore 2, top plate 1
Disk side be equipped with four threaded holes 3 being uniformly distributed along the circumference, be equipped with adjusting screw 4 in each threaded hole 3.Four threaded holes 3
Central axis of the center line with top plate 1.
Embodiment
This example plays table at 5 both ends of column and middle part as shown in Figure 1, by figure clamping, by adjusting chuck 6 and adjusts
It saves screw 4 and achievees the purpose that centering to adjust the position of 5 center line of column.
Or as shown in Fig. 2, press figure clamping, table is played at 5 both ends of column and middle part, by adjusting the adjusting screw 4 at both ends,
It adjusts the position of 5 center line of column, achievees the purpose that centering.
In figure, centering top plate 7 be used for top connection, and support workpiece.Screw is adjusted for adjusting workpiece in top plate
Position.
